About This Scorecard

This is the first statewide Police Scorecard in the United States. It was built using data from California's OpenJustice database, public records requests, national databases and media reports.

methodology Source Data


Use this Scorecard to identify issues within police departments that require the most urgent interventions and hold officials accountable for implementing solutions. For example, cities with higher rates of misdemeanor arrests could benefit most from solutions that create alternatives to policing and arrest for these offenses. In cities where police make fewer arrests overall but use more force when making arrests, communities could benefit significantly from policies designed to limit police use force. And cities where complaints of police misconduct are rarely ruled in favor of civilians could benefit from creating an oversight structure to independently investigate these complaints.


Here's how to start pushing for change:


  • Contact Your County Sheriff, share this scorecard with them and urge them to enact policies to address the issues you've identified:
    Advocacy Tip:  California's new deadly force law goes into effect in January - requiring departments to adopt more restrictive deadly force policies. Tell your Sheriff to adopt a policy that explicitly requires police to exhaust all available alternatives prior to using deadly force.  Research shows this policy saves lives.
  • Find your US Senator and US Representative using the Campaign Zero Advocacy Tool and urge them to support the PEACE Act, which would require police departments to adopt policies requiring de-escalation and alternatives to deadly force, a change that would reduce police shootings nationwide.
